If you can describe it to us with detail, perhaps someone can give you the answer since your strategy here for hooking speakers up to an HTPC via HDMI won't work.
My ultimate goal is to use my existing HTPC's throughout the house as whole home audio solutions, without having to buy any expensive / bulky hardware (minus speakers and cabling).
I have an HTPC, little ZBox's on the main floor, and bedroom (basement has a theater room and a dedicated small htpc build that is capable of 3D, just a little more powerful than little ZBox's). All run XBMC and are controlled via remotes on our iPhones.
What I had envisioned, in hopes of wife proofing as much as possible, was setting the HDMI out from our zbox to an hdmi splitter (I already have one for testing). Then, a simple remote press would send the signal either to the TV, or to the speakers. Regardless of where it is being sent, the iPhone will control what is played.
I am not aware of an easy way to switch between audio outputs of the little zboxes, and am not aware of a way to dual output audio. So, that is why I came up with this solution.
The other solution is to just go to the zbox and plug in a cable to the headphone jack, which would go directly to a speaker. This is less than ideal, but will work.
So, ultimate goal is to use xbmc box to control audio to external speakers via one app in the iphone. As soon as multiple remotes, physically moving cables / plugging them in, and multiple apps are involved to accomplish this, then this becomes un-wife proof.
Edit - 3 of the 4 htpc's have xbmc live, so linux based.
The theater room AVR has zone 1 and 2 spoken for alredy (11.2 surround), so I can't use that. And, I problably wouldn' use that one anyway, I have 2 other computers in the basement I'd use in it's place.
